Scouting report: Pure point guards are an endangered species in the NBA, but Ennis is one of them. He’s a pass-first pure point guard that utilizes excellent ball-handling skills to create space, which usually leads to open looks for teammates.

Ennis had a highly efficient 3.22 assist-to-turnover ratio, but his statistics probably would’ve been even more impressive had better perimeter shooters surrounded him. Of course, he probably will have that in the NBA, which bodes well for his potential as a distributor.

That increased spacing will also create opportunities for him as a scorer, since he is quite a solid shooter, at 35.3 percent from 3 last year. The Syracuse product is impressive off the dribble, which is normal for point guards, but he can also shoot off the catch, allowing him to play off-ball in a number of different situations.

Ennis is only an average defender and lacks a spectacular first step, so he probably won’t ever become one of the NBA’s top point guards, but he’s going to be a good backup, at worst, with the ceiling of a high-end starter.

How he fits: Ennis would give the Celtics an immediate upgrade at the backup point guard position, and a potential heir apparent to Rajon Rondo, if he’s traded.
